λ-Cyhalothrin is a high efficiency, broad-spectrum type II synthetic pyrethroid insecticide containing α-cyano group. λ-Cyhalothrin is used to control a wide range of pests in a variety of applications. λ-Cyhalothrin is a neurotoxin that targets sodium channels in the membranes of neurons in the central nervous system.In Vitro: The mechanism of λ-Cyhalothrin toxicity produces delay in sodium channel inactivation, which leads to persistent depolarization of the nerve membrane. λ-Cyhalothrin produces membrane depolarization, calcium ion infl ux, and neurotransmitter release from rat brain synaptosomes.
λ-Cyhalothrin possesses estrogenic properties and has an ability to function as a xenoestrogen promoting human breast carcinoma cell proliferation in vitro.
λ-Cyhalothrin has found multiple uses in pest (fleas, cockroaches, flies, and ants) control.
λ-Cyhalothrin is highly effective against the malaria transmitting species of Anopheles.In Vivo: The effect of λ-Cyhalothrin (i.p.) on memory, movement activity, and co-ordination in mice exposed to bilateral clamping of the carotid arteries (BCCA) is investigated. Neither memory nor movement co-ordination are impaired by BCCA or λ-Cyhalothrin. Exploratory locomotor activity is significantly reduced in the BCCA/LCH group. Spontaneous movement activity is significantly reduced in the BCCA/λ-Cyhalothrin group . Exposure to λ-Cyhalothrin coexisting with BCCA decreases motor activity in the mice in 2 subsequent 30-min.
